Anionic Surfactants are surface-active agents with:
Hydrophilic Head: Negatively charged (e.g., sulfate, sulfonate, carboxylate)Hydrophobic Tail: Linear/branched alkyl or aryl chains (C10–C18)Key Feature:
Ionize in water → High surface activity in alkaline/neutral pH| Class | Structure | Example Compounds |
|---|---|---|
| Alkyl Sulfates | ROSO₃⁻Na⁺ | Sodium Lauryl Sulfate (SLS) |
| Alkyl Ether Sulfates | RO(CH₂CH₂O)ₙSO₃⁻Na⁺ | Sodium Laureth Sulfate (SLES) |
| Alkylbenzene Sulfonates | R-Ph-SO₃⁻Na⁺ | Linear Alkylbenzene Sulfonate (LAS) |
| Alpha-Olefin Sulfonates | R-CH=CH(CH₂)ₙSO₃⁻Na⁺ | Sodium C14-16 Olefin Sulfonate |
| Property | Advantage | Test Method |
|---|---|---|
| High Foaming | Ideal for detergents/shampoos | Ross-Miles foam test |
| Detergency | Superior oil/stain removal | ASTM D3050 (soil removal efficiency) |
| Wetting Ability | Rapid surface tension reduction | Du Nouy ring method |
| Cost Efficiency | High activity at low concentrations | CMC measurement (conductivity) |
| Industry | Function | Example Use |
|---|---|---|
| Home Care | Laundry detergents, dish soaps | SLES in liquid detergents |
| Industrial | Metal cleaning, textile processing | LAS in degreasers |
| Food | Emulsifiers in baked goods | Sodium stearoyl lactylate |
